The sulfur nucleophiles, sodium thiosulfate (Na2S2O3) and N-acetylcysteine (NAC) given in maximally tolerated doses did not reduce the hematological toxicity of high dose mitomycin C (MMC) in normal mice. In addition, neither sulfur nucleophile significantly altered the antileukemic activity of MMC. Pharmacokinetic studies of MMC in normal mice, demonstrated rapid plasma elimination (T1/2β = 0.53 hrs) and substantial drug distribution to the bone marrow which was enhanced by NAC. These results demonstrate a lack of MMC antidotal activity for Na2S2O3 and NAC.
